REPORT — 1892. 



Fourth Report of the Committee, consisting of Professor W. C. 

 EoBERTS-AusTEN {Chairman), Sir F. Abel, Mr. E. Eiley, and 

 Mr. J. Spiller, Professor J. W. Langlet, Mr. Gr. J. Snelus, 

 Professor Tilden, and Mr. Thomas Turner {Secretary), appointed 

 to consider the best method of establishing an International 

 Standard for the Analysis of Iron and Steel. (Drawn up by 

 the Secretary.) 



In the previous report of this committee it was mentioned that four 

 out of the five proposed international standards had been prepared and 

 distributed as previously arranged, and that the work of the British 

 analysts was practically completed. Dumng the past year a meeting of 

 the British analysts has been held, and the analytical results have been 

 discussed. It was found that the agreement among these numbers was 

 good, more particularly so in view of the relatively small quantity of 

 material which could be supplied to each analyst, and it was decided fco 

 publish an account of the work of the British chemists so far as the 

 investigation has proceeded. This intention was communicated to 

 Professor Langley, as representing the American Committee, and received 

 his cordial approval. The results now communicated have therefore to 

 do only with the work of the British analysts and with the standards 

 Nos. I, 2, 3, and 4. 



It will be remembered that the analysts entrusted with the investiga- 

 tion in this country were as follows : — 



Mr. 



A. H. Allen 

 W. Jenkins 

 G. S. Packer 

 J. Pattmson 

 E. Riley 

 J. E. Stead 



Sheffield, 



Dowlais, 



Glasgow, 



Newcastle-on-Tyne, 



London, 



Middlesbrough, 



and the Royal School of Mines, London, 



Complete reports have been received from Messrs. Jenkins, Packer, 

 Pattinson, Riley, and Stead, while Mr. Allen, who was prevented by 

 other engagements from completely analysing the samples sent to him, 

 has forwarded a report on the determination of sulphur in iron and 

 steel . 



Unfortunately, the analyst attached to the Royal School of Mines has 

 suffered from a long and serious illness, and his results have not been 

 completed. It has therefore been decided to dispense with his report, 

 and for the present the Royal School of Mines is represented by the 

 work of Mr. E. Riley, whose x'eputation as an analyst is so well known 

 and recognised. 



The report received from Mr. W. Jenkins gave the following values 

 as the results of his analyses : —
